Given that it was launched back in 1977, the chances are that if it came back to Earth NOW most of us wouldn't be able to play the music on it. What format is it in? Not CD, obviously. Was it digital, or analogue? What are the chances of any truly alien species having a compatible music playback system, or even of recognising it as music? Perhaps aliens prefer the Spice Girls (someone has to). Perhaps Mozart will translate into alien as a declaration of war (I know a few pubs like that). Thankfully the chances of it ever being seen again by anything are several orders of magnitude less than those of me winning the British National Lottery, and I don't buy tickets.

Isn't space science exciting?
